1. Refer to Primary pages on page 26 and navigate to
Page 3: program .
2. Use the [

] and [

] keys to highlight the desired channel.
Press the [

] key twice to confirm your choice.
3. Use the [

] and [

] keys to highlight the error limits
option. Then, press the [

] key to confirm your selection
or press the [

] key to return to the previous screen.
4. Use the [

] and [

] keys to highlight the desired
signal parameter . Then, press the [

] key to confirm
your selection or press the [

] key to return to the
previous screen.
5. Enter the desired error limit for the chosen signal
parameter. Press the [

] key to confirm the new value
or press the [

] key to keep the original value. In either
case, you will then return to the previous screen.
6. Repeat steps 4 and 5 as necessary, to program
additional signal parameter error limits.
3.4.1.4 Understanding the error limits
Note the following information about the Sentinel LCT8
error limits:
• The
signal min limit is the minimum acceptable value
for the transducer signal received by the Sentinel LCT8 .
If the signal falls below the programmed limit, the
E1: LOW SIGNAL error is displayed.
• The measured velocity value is expected to be
within the min velocity and max velocity limits. If the
measured velocity is outside the programmed range,
a W3: VELOCITY RANGE warning is displayed.
• The amplitude of the received signal is expected to
be within the amplitude min and amplitude max .
programmed limits. If the signal falls outside these limits,
the E5: AMPLITUDE error is displayed.
• If the fluid soundspeed exceeds that entered in the
normal mode of fluid submenu by more than the
percentage programmed in the NormalMde SoS
error limit, the E2: SOUNDSPEED error is displayed.
• If the velocity changes by more than the programmed
acceleration error limit from one measurement to the
next, the E6: ACCELERATION error is displayed.
• If the SNR is below the programmed SNR error limit, the
W24:SNR warning is displayed.
NOTE: Refer to “Table 14” for more details about errors and
warnings.
